Q: Oh cool, a new RepRap slicer?
A: Yes.
Slic3r
Prebuilt Windows, OSX and Linux binaries are available through the git releases page.
Slic3r takes 3D models (STL, OBJ, AMF) and converts them into G-code instructions for 3D printers. It's compatible with any modern printer based on the RepRap toolchain, including all those based on the Marlin, Sprinter and Repetier firmware. It also works with Mach3, LinuxCNC and Machinekit controllers.
See the project homepage at slic3r.org and the manual for more information.
What language is it written in?
The core geometric algorithms and data structures are written in C++, and Perl is used for high-level flow abstraction, GUI and testing. If you're wondering why Perl, see https://xkcd.com/224/
The C++ API is public and its use in other projects is encouraged. The goal is to make Slic3r fully modular so that any part of its logic can be used separately.
What are Slic3r's main features?
Key features are:
- multi-platform (Linux/Mac/Win) and packaged as standalone-app with no dependencies required
- complete command-line interface to use it with no GUI
- multi-material (multiple extruders) object printing
- multiple G-code flavors supported (RepRap, Makerbot, Mach3, Machinekit etc.)
- ability to plate multiple objects having distinct print settings
- multithread processing
- STL auto-repair (tolerance for broken models)
- wide automated unit testing
Other major features are:
- combine infill every 'n' perimeters layer to speed up printing
- 3D preview (including multi-material files)
- multiple layer heights in a single print
- spiral vase mode for bumpless vases
- fine-grained configuration of speed, acceleration, extrusion width
- several infill patterns including honeycomb, spirals, Hilbert curves
- support material, raft, brim, skirt
- standby temperature and automatic wiping for multi-extruder printing
- customizable G-code macros and output filename with variable placeholders
- support for post-processing scripts
- cooling logic controlling fan speed and dynamic print speed
How to install?
You can download a precompiled package from slic3r.org; it will run without the need for any dependency.
If you want to compile the source yourself follow the instructions on one of these wiki pages:
Can I help?
Sure! You can do the following to find things that are available to help with:
- Pull Request Milestone
- Please comment in the related github issue that you are working on it so that other people know.
- Items in the TODO wiki page.
- Please comment in the related github issue that you are working on it so that other people know.
- Drop me a line at aar@cpan.org.
- You can also find me (rarely) in #reprap and in #slic3r on FreeNode with the nickname Sound. Another contributor, LoH, is also in both channels.
- Add an issue to the github tracker if it isn't already present.

How can I invoke slic3r.pl using the command line?
Usage: slic3r.pl [ OPTIONS ] [ file.stl ] [ file2.stl ] ...
--help Output this usage screen and exit
--version Output the version of Slic3r and exit
--save <file> Save configuration to the specified file
--load <file> Load configuration from the specified file. It can be used
more than once to load options from multiple files.
-o, --output <file> File to output gcode to (by default, the file will be saved
into the same directory as the input file using the
--output-filename-format to generate the filename.) If a
directory is specified for this option, the output will
be saved under that directory, and the filename will be
generated by --output-filename-format.
Non-slicing actions (no G-code will be generated):
--repair Repair given STL files and save them as <name>_fixed.obj
--cut <z> Cut given input files at given Z (relative) and export
them as <name>_upper.stl and <name>_lower.stl
--split Split the shells contained in given STL file into several STL files
--info Output information about the supplied file(s) and exit
-j, --threads <num> Number of threads to use (1+, default: 2)
GUI options:
--gui Forces the GUI launch instead of command line slicing (if you
supply a model file, it will be loaded into the plater)
--no-plater Disable the plater tab
--no-gui Forces the command line slicing instead of gui.
This takes precedence over --gui if both are present.
--autosave <file> Automatically export current configuration to the specified file
Output options:
--output-filename-format
Output file name format; all config options enclosed in brackets
will be replaced by their values, as well as [input_filename_base]
and [input_filename] (default: [input_filename_base].gcode)
--post-process Generated G-code will be processed with the supplied script;
call this more than once to process through multiple scripts.
--export-png Export zipped PNG files containing slices instead of G-code.
-m, --merge If multiple files are supplied, they will be composed into a single
print rather than processed individually.
